Those who have gone astray, whom the spirit begets, usually go astray also because of the Spirit. Thus, by one and the same breath, the fire blazes and is put out. (Gospel of Philip) Knock on yourself as upon a door, and walk upon yourself as on a straight road. For if you walk on the road it is impossible for you to go astray. And if you knock with this one, (Wisdom), you knock on hidden treasures. (Teachings of Silvanus)
